Keeping the task group on task

With no commercial floating petrol stations in the middle of the ocean, Royal Australian Navy ships and helicopters rely on specialized replenishment ships for all their fuel needs.

The Australian Navy has two underway replenishment ships, HMAS Ships Sirius and Success – which with the support of similar Allied vessels, keeps the Australian Navy steaming across the globe. For a task…
